On some vessels, the hole shot can often suffer due to the extreme exhaust flooding that occurs around the blades during acceleration. [links]
This is fairly common. Propellers that aren't showing any signs of impact may still have been damaged. Bent or distorted blades will cause the motor to vibrate even if the damage is indiscernible.
Pitch is the second number listed in the propeller dimensions.
Over/Thru-hub exhaust propellers are a combination of thru-hub and over-hub exhaust. [links]
This allows some exhaust to escape at lower RPMS, providing a controlled amount of exhaust flooding. [links]

• Excellent durability and corrosion resistance. here
Developed for the DPX high-speed drive to provide maximum performance and efficiency in speeds up to 75 knots. The high-performance blade geometry and great strength ensure maximum grip and maneuverability. Made of high-strength stainless-steel for excellent durability and corrosion resistance. Shock-absorbing rubber bushing and galvanic isolation makes it perfectly matched for the DPX high-speed drive.
• Designed for speeds up to 75 knots. [links]
• Galvanic isolation protects the drive from corrosion caused by the propellers.
The stainless-steel DP-E propeller is specially developed to handle the high forces of the DPX high speed drive. Handling speeds up to 75 knots put high demands on the propeller’s performance. more
Don't use SSteel, it'll gall the threads, 'n rip 'em right off the shaft.
This is a fresh rebuild. New rings, compression is good. Idles good.. is it possible that its cause its not under load? Or maybe idle mixture? here
I must also add, I still have that rough spot in my RPMs (about 2500 RPM). Here's the video again if anyone wants to maybe reply to this thread with a clue: http://youtu.be/lAQS0XEuB0Y
